People in the Ming Dynasty liked brightly colored things the most, so these glasses could be made into crafts such as enamel bottles, which would definitely sell for a lot of money.

In the third experiment, Li Yi saw with his own eyes that the craftsmen made transparent glass. Then the craftsmen used the air blowing method to create a palm-sized flat glass, pasted tin foil on it, poured mercury on it, and a mirror was made.

Out.

However, the reflectivity of the back of the mirror made of mercury is not that good. It can be improved to silver plating in the future. This technology still needs some time to study.

Moreover, the air blowing method can only produce flat glass at present, and the flat glass produced is still very small and cannot be made very large. Therefore, Li Yi proposed the casting method to the craftsmen to produce larger flat glass. The craftsmen all have

The skills of generations of people are also very superb, and they have a high understanding of this production process. Li Yi just gave a rough outline, and they were able to figure it out quickly.

Now that glass has been produced, it can not only become a luxury commodity in this era, but also greatly promote the development of optics. Li Yi wants to produce the most practical mirrors and telescopes in batches as soon as possible.

Looking at the tired faces of the craftsmen who often stayed up late, Li Yi was also very grateful to them. Without their hard research, neither glass nor cement would have appeared so quickly.

Li Yi asked the secretary next to him to record the achievements of the craftsmen. While encouraging them, he also warned them not to reveal all the technology of the institute, not even to their family members, because it was related to An Xin's life and death.

Hearing that these technologies were so important, the craftsmen all solemnly agreed. They are now tied to Anxin. Once problems arise in Anxin, it will be difficult for them to escape. Even if they can leave, leaving Anxin, they will gain nothing.

The merits will be useless and you will become a refugee again.

This was Li Yi's intention when he came up with the merit system, which was to tie the refugees to his warship forever and try to avoid traitors.

After seeing the results of the institute, Li Yi turned around and went to the Ordnance Bureau. The Ordnance Bureau now mainly develops firearms. The weapons Li Yi used before were made by the Ordnance Bureau according to his ideas. In the actual combat test that day, the * shrapnel

The killing area was sufficient, but the lethality was not as powerful as expected. Many of the servants who were in the explosion range at that time only had some external injuries, which were far from fatal.

The Viper was the first army to use this weapon in actual combat, so Li Yi asked the snakehead to write down the test results of the day and handed them to the Ordnance Bureau so that they could improve them and increase the weapon's lethality.

What Li Yi went to check out today was the gun that he had previously given to the Ordnance Bureau to develop, a future rifle that existed in his mind.

This kind of rifle uses a flintlock gun to ignite and does not require a match rope, which greatly improves the operability of the rifle. The rifle bore is engraved with rifling, and iron lead bullets with a tapered hollow tail are used for front-loading shooting. Due to the pressure of the rifling, the lead

After the bullet is fired, it spins at high speed and flies very stably. The range is increased. Such a rifle can hit targets four or five hundred meters away. It is definitely a big killer in this era.

The core of this technology is that craftsmen have developed simple machine tools for making rifling.

Because he knew that the future would be a war dominated by thermal weapons, Li Yi wanted to increase the firearms equipment rate of his army, so that all members of the private camp would be equipped with flintlock guns and a large number of light artillery, forming an army dedicated to attacking fortresses and breaking formations.

Hot weapon army. This kind of army can basically smash the cold weapon army of this era into rubbish.

Of course, the current cold weapon army is still very powerful, so Li Yi is also focusing on forming Yongying and Hanyong so that they can form a defense line for the private camp and deal with the opponent's close combat. Such multiple arms are composed of cold weapons and hot weapons.

The army has the most combat effectiveness and vitality.

Due to the shortage of iron ore, Li Yi is temporarily unable to produce artillery, and artillery casting technology is difficult and will not be developed in a short time. However, the manufacturing technology of flintlock guns is not difficult. Li Yi only needs to draw the design.

The craftsmen who made muskets in the Ming Dynasty could imitate them.

The parts of the flintlock bolt can be made by craftsmen according to the drawings and then assembled. The only new thing is a manual broaching machine. However, this kind of broaching machine does not require high precision. Li Yi also designed the drawings after thinking hard, and then

He expressed his ideas bit by bit and let the craftsmen make modifications, and finally the simple machine tool took shape.

The first thing to make when making a gun is the barrel. The better the iron quality, the less likely it is to explode the barrel. Anxin's iron is produced in a blast furnace and can be turned into steel, so the quality is very good.

In the past, the craftsmen of the Ordnance Bureau beat the steel into sheets, then heated the wrought iron sheets red, placed a circular steel bar in the middle, and repeatedly turned and struck the wrought iron in a steel semicircular groove.

Knock the piece into the shape of a gun barrel, then use iron powder and borax to weld the gap, and beat repeatedly until the weld is firm.

After the barrel is formed, the craftsman puts the barrel on a drilling tool to drill, apply oil on the drill bit, replace it with a larger drill bit bit by bit, and plan away the uneven spots inside the barrel bit by bit until the gun is

A smooth bore is drilled into the tube.

This drilling process is the most time-consuming, and a skilled craftsman will have to drill for several days to drill out a qualified barrel. Once the barrel is ready, most of the gun manufacturing is completed, and the rest of the work is done next.

It's all simple.

After the barrel is made, it is necessary to put four times the normal explosive force in the barrel and explode it once. If the barrel does not crack after the explosion, the barrel will be used! Barrels with cracks will be treated as scrap.

Yes! After this step of inspection, the finished bird gun will not be boring.

The reason why the Ming Dynasty's fireguns exploded a lot was because the officers withheld materials, resulting in insufficient material for the barrels. They originally used four times the test force, but they found a way to use twice or even half the test force.

It's strange that the explosion rate is not high.

Therefore, it is not objective enough to explain that the combat effectiveness of the Ming Dynasty army is low. The army in the late Ming Dynasty did not have enough to eat, so they exchanged armor for food. They could not get wages, so they did hard work to support their families. When they encountered the enemy, they wore

He was wearing single clothes, holding inferior weapons in his hands, and obeying the orders of a group of civil servants who only knew about party struggle with an empty stomach. It was simply impossible that he would not lose this battle.

Therefore, Li Zicheng did not defeat the Ming Dynasty, and the Manchu Qing Dynasty did not defeat the Ming Dynasty. What defeated the Ming Dynasty was its decadent ruling group.

Li Yi walked into the Ordnance Bureau and saw that the craftsmen were discussing and drawing in full swing. He did not interrupt, but looked at the design drawings of the flintlock gun and the broaching machine next to him. Although the original drafts of these drawings were drawn by himself

Yes, but after the improvements made by the craftsmen, I can no longer understand it. After thinking about it for a while, I finally figured out the structure.

It has to be said that the skills and experience of these master craftsmen are really unimaginable. As long as they are given a suitable environment, Li Yi doubts that they can develop advanced lathes.

Looking at the lathes in the workshop, each broaching machine has an iron rod fixed on it. There are threads cast on the rod. When the rod moves back and forth, the thread must pass through a fixed card door on the broaching machine. The rod can move at a constant speed under the action of the thread and the card door.

Rotate. There is a steel ball embedded at the end of the pole that extends into the barrel of the gun. Multiple layers of thick paper can be placed under the steel ball. By thickening the paper a little bit, the protrusion of the steel ball can be gradually increased to grind the inner bore of the barrel.

Grind out the rotating rifling bit by bit.

This kind of broaching machine does not require high precision, as long as the drawn rifling can force the bullet to rotate. Even the gunsmiths in the 19th century later built such broaching machines purely by hand.

With this kind of lathe, the time for making firearms can be shortened by more than half, which greatly increases the output of firearms. This is the complete reason why private firearms are equipped so quickly.

"Little benefactor, why are you here?" After discussing the issue of lead bullets with the craftsman, Mr. Liu turned back to drink water and happened to see Li Yi.

"I came to take a look. Seeing that you were so busy, I didn't bother you. By the way, have you finished making the flintlock gun I asked you to make before?" Li Yi asked.

"The first batch of ten has been made. Today we just made several hundred rounds of bullets with hollow tails out of lead. Now we can test-fire." Liu Dajiang said.

Time was running out, so Li Yi quickly asked them to experiment for himself.

The apprentice set up wooden targets as tall as one person on the sand outside, placing them at two hundred meters, three hundred meters, four hundred meters, and five hundred meters.

Five flintlock guns were tested separately. The worst one only missed the target three out of five times when shooting 300 meters away. The best one hit the target 300 meters away again and again, and the one-inch-thick gun missed the target again and again.

The wooden target punched holes one after another.

Such achievements made the craftsmen who were watching marvel. They must know that the Ming bird gun they are familiar with can hit a target of fifty steps at most, and the hit rate of a target 100 steps away is only 20% to 30%. If it hits a target of 140 steps,

In other words, a target of about 200 meters is purely random shooting. If you can hit one shot out of ten, you will have to burn a lot of incense.

And the worst one among these ten flintlock guns can reliably hit the target 140 steps away. How miraculous it is. They simply feel that their half-life muskets have been in vain.

It’s only today that I feel like the sun is clearing from the clouds.

The flintlock gun was tested, and the surrounding guards also ran out to watch the fun. When they watched the flintlock gun hit the wooden target two hundred meters away again and again, their eyes lit up with excitement.

You must know that they are all rural warriors. The most likely thing is to hold positions in the militia in the future. Most of the weapons they master are firearms. If they are equipped with such weapons, then no army can be their opponent at a long distance.

The best-performing flintlock can not only hit a target two hundred meters away, but can also accurately hit a target two hundred paces, or three hundred meters away, again and again, hitting the thick wooden target into a

Sieve. Not only that, this gun can hit the target four hundred meters away, with a hit rate of 60%, and can even penetrate the wooden board. This gun can even hit the target five hundred meters away, with a hit rate of 60%.

It is also much larger than the blunderbuss.

You must know that shooting at a distance of 400 meters or 500 meters is not a question of whether the gun is accurate at all, but a question of whether the shooter can aim at such a distant target. In other words, if the shooter is in perfect condition

Aiming accurately, this gun has a theoretical range of more than 500 meters!

Five hundred meters, that's a mile. The infantry in the cold weapon era was not ready to charge even a mile away, and you would have been killed by one shot here.

If they hadn't seen it with their own eyes, how could these five craftsmen believe that such firearms were made by themselves?

Even the onlookers, Xiang Yong, stared at this scene with big eyes and small eyes. They were so surprised that they couldn't even utter exclamations. What is the concept of taking a human life from a few hundred steps away? The story told by the storyteller also said

I don’t dare to brag like that! Looking at the back, the military households seemed to have seen the magic soldiers coming down to earth, and none of them dared to show off.

Not only that, this kind of musket does not require a ignition rope, but can be fired with a flintlock. In the past, when the musket shooter took aim, he had to always be on guard against having his eyes and eyebrows burned by the match rope, but now there is no need to worry.

Using a flintlock gun, the shooter can aim steadily. When shooting, there is no need to install a match rope, ignite the match rope, blow the primer, and test the match rope. This saves several steps and the shooting speed is also greatly improved.

The craftsmen finally understood why the little benefactor emphasized secrecy so much. Just this weapon is an unprecedented artifact. All existing firearms can only surrender in front of this blunderbuss. Armed with such a weapon

How powerful is the army?

With an army equipped with such firecrackers, the little benefactor will definitely be invincible in the future. When everyone was shocked by the effect of the flintlock gun, they also thought of its meaning, and looked at Li Yi,
Chapter completed!
